2N® Analog Intercom door communicator has implemented a Half duplex hands free algorithm which is tuned for the most common installations.
If you have a specific installation (noisy background, etc ... ), please try following:
- In case of noisy background, please set PIN for microphone sensibility on Jumper 8 (see manual page 23)
- See audio parameters from 931 to 938 and try to set different values with your best meaning (see manual page 34)
- Ground the unit. In case of Force and Safety is mandatory to have it grounded for correct handsfree function.
- In case it does not help, send the record of the communication on analog line to technical support (could be possible with help of recording device order no. 18025801).
